| 摘 要： | We study the effect of electrodes with varying thickness on thickness-twist vibration of a piezoelectric plate resonator of crystals of 6 mm symmetry.An exact theoretical analysis is performed.Results show that non-uniform electrodes have a strong effect on mode shapes,and suggest the possibility of using nonuniform electrodes for strong energy trapping.
